(the operation cannot be completed
Error while erasing flash operation failed Memory set failed)
I have tried other laptop but still the same

Please tell me what is this problem

Thank's in advance guys

Sounds like noise on the USB lines. I have found that some laptops have more reliable communications if the A/C adapter is disconnected. Give that a try.
